What is the URL scheme that is used by Bitcoin to copy transaction information directly into the client? Which versions of Bitcoin clients support it?

The Bitcoin Improvement Proposal that defines the Bitcoin URI scheme is BIP21.

The simple syntax is:

bitcoin:<address>[?amount=<amount>][?label=<label>][?message=<message>]

On the desktop all of Armory, Electrum and MultiBit respond to Bitcoin URI clicks in a browser and I believe Bitcoin-QT V0.7 does as well.

On mobiles Android Bitcoin Wallet does. On the iPhone the blockchain.info app does.

    Bitcoin-Qt v0.7 for Windows does. Not Mac or Linux yet. – Stephen Gornick Oct 11 '12 at 20:56

    It's important to note that although it isn't specified in the simple syntax, '?' after the first are changed to '&' as in regular URLs. For example: bitcoin:<myaddress>?amount=1&message=mymsg – Kevin Cox Jan 13 '14 at 23:02

    Not to nitpick, but the acronym "BIP" stands for Bitcoin Improvement Proposal instead of Bitcoin Improvement Process. – Priidu Neemre Mar 26 '15 at 15:19
  • Apparently the number of decimals in the BTC amount matters. My wallet was rejecting the uri until I reduced the decimals to eight. – KalenGi Feb 10 '16 at 8:57
